在 except 后面应该填写 ZeroDivisionError,因为这个错误是由于除数为0导致的。正确的代码应该是:
a, b = eval(input())
try:
print(a / b)
except ZeroDivisionError:
print("第二个参数不能为0!")
finally:
print("程序结束")

a , b = eval ( input ()) try : print ( a / b ) except ①: print ("第二个参数不能为0!") finally : print ("程序结束")
The code snippet above takes two inputs, a and b, and tries to divide a by b. If b is 0, it will raise an exception and print "第二个参数不能为0!" (which means "the second parameter cannot be 0!" in Chinese). The finally block will always execute and print "程序结束" (which means "program ends" in Chinese).
However, there is an error in the code. The except block is missing an exception type, which means it will catch all exceptions. This is not recommended as it can hide potential bugs in the code. A better approach would be to specifically catch the ZeroDivisionError exception like this:
a, b = eval(input())
try:
print(a / b)
except ZeroDivisionError:
print("第二个参数不能为0!")
finally:
print("程序结束")
a, b = eval(input()) try: print(a / b) except ZeroDivisionError: print("第二个参数不能为0!") finally: print("程序结束")
这是一个使用 try-except-finally 结构的 Python 代码片段,它接受用户输入的两个值,将它们分别赋值给变量 a 和 b。然后,它试图计算 a 除以 b 的结果,并在除数为零的情况下捕获 ZeroDivisionError 异常,并输出一条错误消息。最后,无论是否出现异常,程序都会输出一条“程序结束”的消息。
